EDWARD E. BRADLEY, OF STONINGTON, CONNECTICUT, ASSIGNOR TO THE ATWOOD MACHINE COMPANY, OF STONINGTDN, CONNECTICUT, A CORPORATION OF NEW JERSEY.

QUILLING-MACHINE.

Application filed April 19, 1913.

To all whom it may concern:

Be it known that I, EDWARD E. BRADLEY, a citizen f the United States, and resident of Stonington, in the county of New London and State of Connecticut, have invented a new and useful Improvement in Quilling- Machines, of which the following is a specification.

My invention relates to quilling machines with the object in view of improving their efliciency and to this end, my invention consists in certain features of construction and combination of parts as will be hereinafter described and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in side elevation, partly broken away, of so much of a quilling machine as will suffice to illustrate my invention. Fig. 2 is a transverse vertical section on an enlarged scale. Fig. 3 is a partial side elevation on the same enlarged scale with certain parts removed. Fig. '4; is a partial horizontal section on a still larger scale,

taken in the plane of the line AA, Fig. 3. Fig. 5 is a partial vertical section in the plane of the line B-B, Fig. Fig. 6 is a partial vertical section in the plane of the line C-C, Fig. 1, and Fig. 7 is a top plan view of the gearing for transmitting motion from the spindle driving belt to the shafts for operating the traverse motion cam.

The supporting frame of any wellknown or approved form, is denoted by 1. In this frame two banks of spindles for receiving the quills are supported as is usual. In explaining the invention, detailed reference will be made to one bank only, it being understood that the detailed structure applies to the other bank as well and furthermore, the parts which intimately coact with each spindle of a bank are repeated with the other spindles of the bank requiring a detailed description of one set of these coacting parts.

A spindle is denoted by 2, a quill frictionally seated thereon for receiving the thread by 3, a spindle whirl by 4, the driving belt by 5, and the driving pulley actuated from a. source of power not shown, by 6. These parts may be of any well known or approved form. The thread carrier, denoted by 7, (see Fig. 5) and the carrier support 8, are flanged" to form a raceway Specification of Letters Patent.

Serial No. 762,378;

for balls 9, so that when assembled, the carrier 7 will be suspended on ball bearings. The carrier support has a sleeve portion 10,

which moves up and down with the traverse rod 11, and has a movement relative to said rod as follows. The rod 11 has series of rack teeth 12, and 13, on its opposite sides (see Figs. 5 and 6) adapted to be engaged by spring actuated pawls 14 15, mounted by means of handles 16, ll, in pairs of ears 18, 19, projecting from the sleeve 10, the sleeve 10 being slotted to permit the pawls 141, 15, to extend through into engagement with the teeth 12, 13. The pawls lat, 15, are conveniently made of strips of metal and extended underneath the handles l6, 17, to which they are secured and given a bearing against a raised portion 20 of the sleeve 10, to hold the noses of the pawls yieldingly in engagement with the rackteeth. The rack teeth 12, 13, are so set that the carrier support 8 and its sleeve 10, may be forced-upward, the noses of the pawls riding over the teeth, but may not be forced downward unless the pawls are positively disengaged from the teeth by pressing inwardly on the handles 16, 17;

hence, as the thread carrier is crowdedupward by the filling of the quill, its support will ride up on the rod 11 tooth by tooth, the traverse motion being the same in ex tent but traversing a portion of the quill extending upward a little farther and not quite so far downward as before the carrier support was shifted.

To hold the traverse rod 11 accurately in position during its movement up and down with the carrier support thereon, its upper end is received in a tube 21 fixed to and depending from an arm 22 supported bya bracket 23, uprising from a beam 24; connected to the end frames of the machine. The exterior diameter of the tube 21 is made to correspond to the exterior diameter of the the teeth 26, 27.

the tube 21, the pawls 14, 15, serving to hold it on the tube 21 by their engagement with The tube 21 thus serves the double function of a guide for the trav erse rod 11 and a temporary support for The the thread carrier and its support. thread carrier support is further provided with a lateral extension 28 having a recess 29 in its end, the walls of which partially embrace a rod 30 supported at its upper end in the arm 22 and extending down through the bed of the machine to serve as a guide as will hereinafter appear. The engagement of the extension 28 with the rod 30, prevents the thread carrier support from turning laterally on the traverse rod. -A collar 31 provided with a set screw 32, may be locked in different vertical adjustments on the rod 30, tolimit the downward movement of the carrier support. tripping pin'33 has a screw-threaded engagement with the thread carrier support and may be raised and low ered by screwing it in or out of the support. The spindle is stopped at the desired moment during the operation of winding the thread on the quill either before the quill is completely filled or upon the complete filling of the quill by the engagement of the tripping pin38 with a latch 34, hinged in a bracket 35, secured in vertical adjustment to the bracket 23, by means of an elongated slot 86in the, bracket 35, and a set screw 87 extending through the slot 36, into the bracket23. The latch 34 has a lateral promanually operating it if necessary. I The jection 38, (see Fig. 4) in the vertical path of the tripping pin 33, the outer end of the latch being flattened as shown at 39, for

inner end of the latch curves downwardly in position to overlap the edge of a collar 40, secured bya set screw 41 to a vertically movable rod 42. The rod 42 is guided at-its upper end in a perforated lug 43 on the bracket 23, its lower end projecting through the. bed of the machine, and connected with a manually operated push rod 44, extending upwardly through the bed of the machine, by a yoke 45. The connection is such that the rods 42, 44,, and yoke 45v move as one piece. The rod 42 has a collar 46 adjustably secured thereon by a set screw 47, and a spring 48 interposed between the collar 46 and the bed of the machine is held under compression tending tolift the rod 42 and hence the yoke 45 and push rod 44. An arm 49 is secured at one end by means of a set screw 50, to the push rod 44, .the opposite end of the arm being bifurcated to embrace the upper and lower sides of the tail of a brake lever 51, (see Figs. 3 and 4), hinged at 52, to a bracket 53 on the bed. of the machine, the head ofthe brake lever being provided with a jaw 54, of friction material in position to press down upon the flange at the lower end of the spindle whirl, when the carrier support, engages and lifts the outer end of the latch 84, the rod 42 will be released and together with the yoke 45 and push rod 44, will spring upward, thereby lifting the tail of the brake lever and forcing the jaw 54 into contact with the whirl to stop the spindle. The traverse rod 11 has fixed to its lower end by a set screw 55, a

I hook piece. 56, the head of which is provided with a bore 57 for the receptionof the end of the rod 11,'and for the seating of a cushion spring-58, and the hook portion of which extends under the horizontal, vertically-reciprocating bar-59 carried in the bifurcated upper ends of the pitmen 60, 61. The walls of the bore 57 are cutaway at the lower end ofthe bore above the bar 59, to permit the latter to exert its upward pressure against the spring cushion 58 and through it, transmit motion to the traverse rod 11. The head of thepiece 56 has a lateral extension 62, the end of which embraces and slides on the rod 30 as a guide. The pitmen for the two banks of spindles are reciprocated by bell-crank levers arranged in pairs at or near the opposite ends of the machine. The two members of a pair (see Fig. 2) are denotedby 63, 64, the lever 63 and its companion lever at the opposite end of the machine, being pivotally mounted in axial alinement and the lever 64 and its companion at the opposite end of the machine mounted in axial alinement. The pitman 60 is adju'stably connected with the outwardly extendingarm of the lever 63, and in like manner, a pitman forthe .opposite bank of spindles is adjustably connected 65, tending to hold the levers in engagement with a cam 66, interposed between the levers and common to the two levers, rocking them or permitting them to be rocked under the tension of the spring 65, simultaneously in the same direction as the cam is rotated. Theouter ends of the levers, connected directly with the pitmen, move simultaneously in opposite directions up and down, while their spring connected ends remain the same distance apart and the spring tension on the cam remains constant, giving a steady motion to the traverse and making the change of motion at the ends of the traverse easy. It is to be understoodthat a cam similar to. the cam 66, acts uponthe pair of bell-crank levers at the opposite end of the machine in harmony with the cam 66. A shaft 67 on which the cams are carried is driven by F1 bevel gear 68 on the end of the shaft, intermeshing with bevel gear 69 on a transverse shaft 70, which in turn, is driven by bevel gear 71 on a vertical shaft 72, the latter carrying a spur wheel 73 engaged by a pinion 7% 011 a stub shaft 75, (see Fig. 7 a spur wheel 76 on the stub shaft 7 5, bein engaged by a pinion 77 on a vertical shaft 38, which carries a belt pulley 79 driven by the spindle driving belt 5.

To give threads of different qualities and sizes the most advantageous resistance in each instance, the oval-faced plush covered cushion or girth 80, over which the thread 81 is drawn, is attached to a support 82 provided with a horizontally elongated slot 83, through which the support 82 is secured to a bracket 8% fixed to the main frame and pro vided with a vertically elongated slot 85, by a set screw 86. The screw 86 extends also through the slot 85, and thus serves to lock the support 82 and hence the cushion 80, in different horizontal and vertical positions relatively to the fixed guide rods 87, 88, over which the thread is led, and also in an are about the screw 86. After leaving the cushion 80, the thread is led to and around a guide rod 89. This rod is also made adjustable in an are about its clamping screw 90, and bodily adjustable up and down in an elongated slot 91, in the bracket 84. From the rod 89, the thread is led through a hook 92 on the end of a spring rod 98, hinged on a pintle 94, for example, by coiling it one or more times around the pintle and extending its opposite end into engagement with one or another of several retaining pins 95, 6, 97. As shown in Fig. 2, the tension on the thread from the spring rod 93, is the minimum tension. This may be increased step by step, by engaging the extension of the spring rod with the retaining pin 96 and 97. It is obvious that the retaining pins may be more or less than three and spaced farther apart or closer together as may be found expedient. From the hook 92, the thread is led to the traverse thread guide 98, and thence passes to the quill.

The operation has been so fully described in connection with the explanation of the several parts, that the operation of the whole is deemed unnecessary.

The structure provides for winding quills of varying lengths without changing the traverse stroke; for the prompt suspension of the thread carrier and its support, the effective stopping of the spindle when the quill has been filled to the desired extent, for the cushioning of the traverse rod drive, for operating the traverse rods of the two banks of spindles by a single set of cams and for the accurate adjustment of the tension to suit all varieties of threads.

It is obvious that changes might be resorted to in the form and arrangement of &

the several parts without departing from the spirit and scope of my invention. Hence I do not wish to limit myself strictly to the structure herein shown and described, but

What I claim is:

1.
